Imiqondo eyisisekelo kanye nokuhlukaniswa kwe-cellulose ether

I-Celsulose Ether yisigaba esiguquguqukayo sama-polymers asuselwa ku-cellulose, okwenzeka ngokwemvelo e-polysaccharide etholakala ezindongeni zamaseli ezitshalo. I-Cellulose Afers isetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yezakhiwo zazo ezihlukile, ezibandakanya ukuqina, ukugcinwa kwamanzi, amakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, namakhono okuzinza, nokuzinza kwamakhono. Nayi imiqondo eyisisekelo kanye nokuhlukaniswa kwe-cellulose ether:

Imiqondo eyisisekelo:

1. Isakhiwo seCellulose:
   • I-cellulose yakhiwa ukuphinda ama-glucose amayunithi axhumene ndawonye ngu-β (1 → 4) amabhondi e-glycosiic. Kungamafomu amade, amaketanga aqondile anikeza ukwesekwa kwesakhiwo ukutshala amaseli.
2. Ukuqothuka:
   • I-Cellulose Tashers ikhiqizwa ngokuguqulwa kwamakhembu yi-cellulose ngokwazisa amaqembu e-ether (-Och3, -Och2chKoh,-njll) amaqembu we-hydroxyl (-oh) e-molecule ye-cellulose.
3. Ukusebenza:
   • Ukwethulwa kwamaqembu e-ether kuguqula izakhiwo zamakhemikhali nezingokomzimba ze-cellulose, enikeze izithambisi ezihlukile ezisebenzayo njenge-solubity, i-viscosity, ukugcinwa kwamanzi kanye nokwakheka kwamanzi.
4. I-BiodegradeAbilibility:
   • I-Cellulose Tashers iyi-bymerlines allmers, okusho ukuthi ingadilizwa ama-microorganisms emvelweni, okuholela ekwakhekeni kwemikhiqizo engeyona ingozi.

Ukuhlukaniswa:

I-Cellulose Afers ihlukaniswa ngokususelwa kuhlobo lwamaqembu e-ether angeniswa ku-molecule ye-cellulose kanye ne-degree yabo yokufaka esikhundleni. Izinhlobo ezijwayelekile ze-cellulose afers zifaka:

1. Methyl cellulose (MC):
   • I-methyl cellulose ikhiqizwa ngethula amaqembu we-methyl (-Och3) eMolecule ye-cellulose.
   • Kuyancibilika emanzini abandayo futhi kwakhiwa obala, izixazululo ezibonakalayo. I-MC isetshenziswa njengesikhudlwana, i-stabilizer, kanye nefilimu yangaphambili kuzicelo ezahlukahlukene.
2. I-Hydroxyyethyl cellulose (HEC):
   • I-Hydroxyyethyl celtulose itholakala ngethula amaqembu we-hydroxyethyl (-Och2chCH2OH) eMolecule ye-cellulose.
   • Ibonisa ukugcinwa kwamanzi okuhle kanye nokuqina kwezindawo, okwenza kube lula ukusetshenziswa kupende, anamathela, izimonyo, kanye nemithi.
3. I-Hydroxypropyl methyl cellulose (HPMC):
   • I-Hydroxypropyllylylylylylylyllllulose iyi-copolymer ye-methyl cellulose ne-hydroxypropyl cellulose.
   • Inikeza ibhalansi yezakhiwo ezifana ne-solubity yamanzi, ukulawulwa kwe-viscosity, kanye nokwakheka kwefilimu. I-HPMC isetshenziswa kabanzi ekwakheni, emikhakheni, kanye nemikhiqizo yokunakekelwa komuntu siqu.
4. I-Carboxymethyl Cellulose (CMC):
   • I-Carboxymethyl Cellulose ikhiqizwa ukwethula amaqembu e-carboxymethyl (-Och2Cooh) eMolecule ye-cellulose.
   • Kuyancibilika emanzini kanye namafomu e-viscous solutions enezakhiwo ezinhle kakhulu zokuqina nokuzinza. I-CMC isetshenziswa ekudleni, emikhakheni kanye nezicelo zezimboni.
5. I-Ethyl Hydroxyethyl cellulose (EHEC):
   • I-Ethyl Hydroxyethyl celtulose itholakala ngethula amaqembu e-ethyl kanye ne-hydroxyethyyl e-cellulose molecule.
   • Kukhombisa ukugcinwa kwamanzi kuthuthukisiwe, ukuqina kanye nezakhiwo ze-Rheological kuqhathaniswa ne-hec. I-EHEC isetshenziswa ezintweni zokwakha kanye nemikhiqizo yokunakekelwa komuntu siqu.

I-Cellulose Tashers iyi-polymers ebalulekile enezicelo ezahlukahlukene kuyo yonke imboni ehlukahlukene. Ukuguqulwa kwazo kwamakhemikhali ngokungena ku-echesherication kukhuphuka ekusebenzeni okuhlukahlukene, kubenza babeke izithasiselo ezibalulekile ekwakhiweni kwamapende, anamathela, izimonyo, imithi, imikhiqizo yokudla, nemikhiqizo yokwakha. Ukuqonda imiqondo eyisisekelo nokuhlukaniswa kwezimali ze-cellulose kubalulekile ekukhetheni uhlobo olufanele lwe-polymer ngezinhlelo ezithile.
